Can Robert Redford's "A Walk in the Woods" do for the Appalachian Trail what Emilio Estevez's "The Way" did for Spain's beautiful El Camino de Santiago? I know many people who saw the latter movie were inspired to lace up their boots and walk the 497-mile Camino. The Appalachian Trail, however, is an entirely different beast, stretching more than 2,180 miles between Springer Mountain in Georgia and Mount Katahdin in Maine.

This epic hike, requiring some five to seven months to complete, was the focus of author Bill Bryson's 1998 bestseller "A Walk in the Woods: Rediscovering America on the Appalachian Trail." The memoir details the adventures of Bryson and his long-lost friend Stephen Katz, as they haul their middle-aged butts out into the wild and take on the AT. As expected, it's now also a Hollywood film, with Redford starring as Bryson and Nick Nolte as Katz.

“It’s about friendship — friendship lost and regained,” Redford told Fox13 earlier this year at the Sundance Film Festival. “Which I thought made it more interesting and gave it more depth.”

Added Nolte: “It’s about getting to an age that you wonder if you’re going to make it up the stairs or not.”

Plans to bring "A Walk in the Woods" to the big screen have been in development for almost two decades, with Redford originally attempting to reunite with screen legend Paul Newman, who passed away in 2008. "Paul said, 'Look, Bob, at my age, I don't think I can do this.' So he had to let it go," Redford told the Telegraph.
